[18.0][IMP] queue_job: requeue orphaned jobs

[hoangtrann]

This pr add a secondary attempt to requeue "orphaned jobs" where it stucks in enqueued, not yet make it to queue_job_lock and selecting jobs after db initialization also misses it. Even a server restart would not unblock the job.

This is most likely due to server being shutdown or crash during job enqueue. Manually requeue the job on UI make everything running again.

Hi @guewen,
some modules you are maintaining are being modified, check this out!

Good catch! I kind of remember we had thought about this case when doing the original implementation with @AnizR but maybe it got lost in the various iterations we did.

In deed, we talked about it but I think that it got lost.

Thanks for this patch, I'll review it within the week.

@sbidoul are we good to merge?
